1 Claim.

All of the foregoing and still further objects` and advantages of the invention will become apparent from a study of the following specication, taken in connection with the accompanying drawing in which The single figure is a View in vertical section through a, gas generator constructed in accordance with the present invention.

Referring now to the drawing in detail, it will be seen that the embodiment of the present invention which has been illustrated comprises a cylindrical tank l for the reception of water 2 in its lower portion, said tank being open at its top.

The reference numeral 3 designates a neck which is mounted at an intermediate point in the tank l in spaced relation thereto, said neck 3 having an external flange 4 at its lower end secured to the tank for mounting the neck thereon. It will thus be seen that an annular channel 5 has been provided which receives-a sealing liquid, such as water 6.

Mounted in the neck 3 is a hopper 7 for the reception of the carbide. In its lower end, the hopper 7 is provided with a discharge opening 9 for the carbide 8 which is controlled by a substantially conical valve 10 mounted on an intermediate portion of a rod 11 having eyes 12 on its ends. A hanger 13 depends from the hopper '7Y and has pivotally connected to its lower end portion a lever 14. The free end portion of the leverI 14 is pivotally connected to the lower end portion of the valve stem.

Traversing the top of the hopper '7 is a horizontal bar 15. A coil spring 16 has one end anchored to the bar 15, as at 17, and its other end connected to the upper end of the valve stern 11. The coil spring 16 is always under tension and yieldingly draws the valve 10 toward closed position in the opening 9. Further, when the coil spring 16 is stretched and permitted to retract, said coil springl functions as an agitator for loosening the carbide 8.

Operable in the tank 1 is a pressure controlled bell 18 having its lower portion submerged in the sealing liquid 6. The skirt portion of the bell extends downwardly between the neck 3 and the tank 1 and is spaced therefrom. Gas passages 19` Serial No. 606,047

are provided in an upper portion of the hopper 7.

The valve 10 is shifted to open position' by the bell 18 through the medium of a rod 20 which is pivotally connected to an intermediate portion of the lever 14, said rod extending slidably through the hopper 7 and through an opening 21 provided therefor in the bar 15.

The reference numeral 22 designates a gas outlet pipe which is mounted in the tank 1 and which includes a portion 23 extending horizontally through the neckA 3. A valved coupling 24 connects the pipe 22 with the delivery pipe 25. The free end of the portions 23 is connected with an intermediate vportion of a vertical goose neck 26' which receives the'gas from the chamber above the water 2 in the tank 1. Mounted on the lower end of the goose neck 26 and communicating with said goose neck is a closed receptacle 27, said receptacle 27 being located above the water 2. The receptacle 27 receives condensation from the pipe 22,thereby preventing the closing of said pipe by water of condensation collecting in the horizontal lower portion 23 thereof.

It is believed that the many advantages of a gas generator constructed in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction andin the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

Having thus described my invention, what I claim as new is:

A gas generator comprising a tank for the reception of water, a hopper, for the reception of carbide, mounted in the tank above the water, said hopper having a discharge opening in its bottom, a pressure controlled bell mounted for Vertical reciprocation inthe tank above the hopper, a hanger depending from the hopper, a lever pivotally connected, at one end, to the lower end portion of the hanger, a valve stern pivotally connected to the other end portion of the lever and rising therefrom through the discharge opening into the hopper, a valve fixed on an intermediate portion of the stem engageable in the discharge opening for controlling the discharge from the hopper, a horizontal supporting member traversing the top of the hopper, a coil spring having one end connected to the supporting member and its other end connectedy to the valve stem for yieldingly urging the valve toward closed position, and a rod connected to an intermediate portion of the lever and extending slidably through the hopper for engagement and actuation in a downward direction by the bell.
